Mikhail Gorbachev warns of 'new Cold War'

The world is on the brink of a new Cold War, and trust should be restored by dialogue with Russia, former Soviet leader Mikhail Gorbachev has said.

He expressed alarm about recent Middle Eastern and European conflicts at an event to mark the 25th anniversary of the fall of the Berlin Wall.

Tensions have been raised between the West and Russia over Ukraine, which was part of the Soviet Union.
